Non-linear potentiometer heater control |
摘要 |
A vehicle is provided with an operators cab having a heating system. The vehicle is powered by an internal combustion engine that is a source of heated fluid. Heated fluid from the engine is directed to a supply line where it is carried to a heat exchanger in communication with the interior of the operators cab. A valve having an electrical actuator regulates the flow of heated fluid through the supply line to the heat exchanger. A non-linear potentiometer controls the actuator so that the heat output of the heat exchanger is linear with respect to the operation of the control knob. The non-linear potentiometer drives the actuator so that the valve is opened at an increasing rate until it its fully opened.
